At Printpack India 2019, TRESU Group, together with its regional agent CGSASP, is showing its ancillary solutions for automating ink supply and enhancing quality, efficiency and output on flexographic label and packaging presses. The company is also presenting information about its Flexo Innovator, an inline flexo printing and converting machine for paperboard applications, combining high speed, minimized waste and fast setup times. TRESU’s Ancillary division is highlighting the vital contribution its program of chamber doctor blades and ink supply systems make in optimizing print quality, waste elimination and machine uptime. Covering label, paperboard, flexible packaging, tissue and specialist coating applications, TRESU’s chamber program is available for all web widths between 185 mm and 6000 mm. Using the company’s unique ‘Pressure Control Technology’, the chambers eliminate air contamination and microfoaming, to ensure clean, uniform print on the substrate. A long-life rubber seal system provides an airtight enclosure, preventing leakage, and maintains consistent ink pressure. Ink quality is assured by a liquid barrier, formed between the rotating anilox rolls and the cham...

YPE html PUBLIC “-//W3C//DTD XHTML 1.0 Transitional//EN” “http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd”> 1967 had the Summer of Love, Thurgood Marshall’s confirmation to the Supreme Court and—if you’re a hockey fan—it was the last time the Toronto Maple Leafs won the Stanley Cup. There was also no shortage of engineering news in 1967, including the Apollo 1 disaster, the Saturn V rocket’s first launch and the Concorde’s debut. Here’s another event from 1967 that was arguably just as important but didn’t get nearly as much press: Peter Houldcroft, then Deputy Scientific Director at The Welding Institute in Cambridge, UK began his experiments using an oxygen assist gas to cut a 1mm-thick steel sheet with a 300W CO2 laser. This marked the beginning of using lasers for industrial material processing. Now, 50 years later, laser cutting machines account for the largest segment of the metal cutting machine market, which also includes plasma, waterjet and mechanical cutting. In the simplest terms, a CNC laser cutter uses a coherent beam of light to cut material, most often sheet metal, but also wood, diamond, glass, plastics and silicon. Broadly spe...
